I'm going to need to recalibrate after larger tires and body lift. I am not interested in all the performance programmers because all I want to do is fix the tire size, shift points, etc. What does everyone recommend? I believe the main options are: factory reprogram at the dealer, Superchips TirePaq and ProComp/Hypertech unit. What have you'll had success with? I want to go ahead and have all my parts lined up and ready at once. I don't want to be figuring out what to purchase after I already have the tires on.
